Toxic Plastic Smell
I used my air purifier for years 24/7. It is a great machine, very quiet and efficient. I loved it. However, the newer filters have a sickening plastic smell which makes it unusable! I have always bought my filters directly from Blue Air, so they are legit. They even replaced the last filter (due to smell), but the new one stinks just as bad. We couldn’t even stand to use it when our AQI was ~500. I am now stuck with an unusable purifier. Blue Air must have changed suppliers or formula. ☹️

Six Months of dust…You won’t believe it!
This filter is seriously impressive! After the recommended six months, I pulled it out expecting some dust—but I was shocked by how much it had actually collected. It was completely layered with dust and looked absolutely disgusting! 😳
It’s amazing to see just how much dust this filter catches and keeps out of the air. Six months later, the proof was right there on the filter. If you’re wondering whether it really works, just look at what it collects!
